IMPLEMENT FOR JOINING IEAGKAGE BINDERS.

Specification of Letters Patent.

Application filed January 6, 1919. Serial No. 269,752.

T5 0. L whom 'it may concern Be it known that L'Srnivonn C. CA Y, a citizen of the United States, residing at the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented a certain new and useful I1nplement for Joining- Package Binders, of which the'following is a specification.

The invention is a press for joining the lapping end portions of a package binder, composed of metal strapping or wire.

In prior applications Serial Nos. 2%,991 and 267,937, filed by me on July 27, 1918, and Dec. 23,1918, respectively, there are disclosed novel forms of devices for securing and sealing binders, whether of wire or strap iron, used for binding shipping boxes and packages. Generally staterhsaid devices embody a splice memberwith one or more loop or bridge members adapted by compression to be looked with the end portions of the binder, but prior to such compresslon the splice member is in an open condition for facilitating its application to, and adjustment to a desired position upon, the meeting portions of a binder.

The implement of this invention is especially designed for closing the splice member and for Q-fEGCtlHg a locking engagement between the splice member and the respective end portions of the binder.

It to be noted that the binder and the locking means therefor require to be applied and secured while remaining in close contact with the shipping package, in order that there may be no appreciable slack be tween the package and any part of the binder, and, further, that the splice member shall be locked to the binderso as to lie substantially in the plane of said binder, thus swuring adesirable' compact or flat relation of the splice member to the surface of the package, as a result of which the packages can be stacked or piled firmly or solidly one upon the other wlthout t1lting said packages. 7

Owing to the close relation'between the binder and the package due to the fact that the binder is stretched or applied under tension by an appropriate tool, and to the requirement that the metal of the binder and Patented Apr. 4, 1922.

the splice member shall be upset in effecting the interlocking engagement between the parts, the tool or implement of this invention 1s constructed with special reference for use upon binders which are under tension around the'package and, also, to afford a powerful leverage in a relatively small and compact implement whereby the desired locking engagement of the splice member to the binder may be secured, and Without in the formation of the cooperating jaws with complemental recesses and ledges resorting to other toolsor fasteners or utiliz- I adapted in the relative movement of said jaws for retaining the splice member and the binder inthe desired relation so as to preclude displacement of the splice member during the operation of compressing its loop or loops and of upsetting the binder for the accomplishment, of the primaryfunotion in. effecting the interlocking engage ment betwemi. the splice'member and the binder.

In a preferred form, the

implement is constructed with a lower jaw which is relatively thin to facilitate the operation of fitting it below the binder and splicemember, said lower jaw having on its working face a plurality of ledges separated by an intervening channel the bottom of which is in the plane of the upper face of said jaw. The lower jaw is formed with a handle and with upstanding flanges, which flanges alford the means whereby the pivots are supported for an upper jaw and for a lever. Said upper jaw is formed on its under face with a ledge positioned in a. plane above the under face 'anc'l'producing a gro-ovebetween two other the depth of which other channels channels, exceed the depthof the groove. The jaws are so assembled that the ledge of the upper jaw is opposite to the channel in the lower jaw, whereas the ledges of the lower jaw are opposite the channels of the upper jaw. The described. formation of the jaws perform the function of retaining the splice member against displacement during the relative movement of the jaws, more particularly the pivotal movement of the upper jaw toward the lower jaw, and the further functions of compressing the loops of the splice member and of upsetting the binder so as to compres the splice member into the plane of the binder and to effect the desired interlocking engagement between said splice member and the binder.

Other features and advantages of the invention will appear fnom the following description taken in connection with the drawwherein- 1g. 1 is a vertical central section partly in e evation of the improved implement showin the jaws opened.

Fig. is a similar section with the jaws closed, the plane of the section being in-- (licated by the dotted line 2-2 of Fig. 3.,

Fig, 2 is a perspective of a part of the lower jaw.

Fig. 3 is a cross section on the line 8-3 of F 1g. 2.

Fig. 4 is an under plan view of the movable jaw. Fig. 4* per aw. a V F igs. 5 and 6 are top and bottom plan views of the splice member and the binder afte said parts are interlocked.

The lower jaw A is constructed in a way to secure the required strength and to be relatively thin in cross section, the forward end portion a bein tapering to facilitate its entry between 51c box and the stra This jaw is provided with a suitable handlb bar A preferably integral'with the jaw, and at. the side portions saidj aw is provided with longitudinal flanges b which are fashioned to produce lugs 12.

B is the upper jaw composed of a relatively fiat metal plate, the same being positioned between flanges band lugs b and one end portion of said jaw being hung on a pin 0, the latter passing through flanges 7) whereby the upper jaw is pivotally mounted at the rear portion thereof. v

A spring C is positioned intermediate the jaws and acts to lift the upper jaw away from the lower jaw for the purpose of introducin the binder and the splice member between %he jaws. As shown, the spring is retained in sockets c is a perspective ofpart of theupprovided in the oppos- V ingz faces of the jaws.

, j The jaws are closed together by the move ment offa lever D, the latter being of any appropriate length and constructed so that it wil have the movement and power re qnired for efi'ectively upsetting the metal so as to interlock thesplice member and the A part only of thislever is shown, but the lever bar is enlarged to produce a head d, one edge portion of which is eccentricto the axis of movement of the lever, thus resulting, in a cum 6. The lever head ,lies between the lugs. b, and said'lever is fulcrumed b a pin f which passes throu h the lugs an the lever head, whereby t e lever is pivotally connected with the ower jaw and it is positioned for the cam e to ride upon the upper jaw when moving the lever toward the left in Figs. 1 and Suitable means are or may be provided for arresting the movement of the lever; as shown, the head dis formed with a sto "surface 9 adapted to bite upon the 'aw when the operation of upsetting; the indler and the splice member is effected. It is a parent that other-means for-arresting t e lever may be provided by a skilled mechanic, but it is desirable to provide some stopping means for the reason that the operator must pull the lever over far enough to bring the stopping means into action in order to effectively lock the splice to the binder.

The opposing faces of the jaws, termed the working faces, are desirably fashioned for upsetting, the metal. As shown, the flanges b of the lower jaw terminate backwardly of theforward end a of 'said jaw, and on the upper face, said lower jaw is formed with a plurality of ledges h h which are separated by an intervening channel it, see Figs. 2 andc3. The upper jaw is formed on its under face with a plurality of channels i i and with a ledge 72, the latter bein intermediate the channels, see Figs. 3 an 4. The height of ledge 71: is less than the depth of channels i so that a recess Z is formed between the under face of the led e 7e and the under surface of the jaw, as clear y shown in F ig. l.

The channel h between the ledges h of the lower jaw receives the splice member P in such manner that movement, of said splice member relatively to the jaw is preeluded by said ledges, thus effectively retainin the splice member in position prior to closin the jaws upon the splice member and the flipping portions ofthe binder. As noted, the height of the ledge 7c on the upper jaws is less than the depth of the channels 2', so as to make provision for the accommodation of the three thicknessesof metal comprised in the two end portions 0 0 of the binder and. the, loop p of splice member P, and when pressure'is ap liedby the co-opcrating jaws, the lodge is of the upper jaw and the ledges h h ofthe lower jaw mutually the working faces to oppose each other ,thus,

the ledges h of the lower jaw are opposite to the channels 2' of the upper jaw, whereas the ledge is of the upper jaw is opposite the channel it of the lower jaw.

The material to be operated upon is shown as a fiat metal strap 0 and a splice member P, said splice member having a single loop or bridge member p, although a plurality of such loops or bridge members may be used as disclosed in my prior applications.

In operation, the end portions of the binder O are engaged by the splice member P after the binder shall have been placed under tension, said loop 12 of the splice member being open as shown in Fig. 1 so that the splice member may he slipped easily upon the binder and adjusted thereon to the required position relatively to the two lapping end portions of said binder. With the lever D swung forwardly and the aws A B opened, see Fig. l, the nose a of the lower jaw is thrust below the binder and the splice member until said splice is between the working faces of the two jaws. The lever is now turned toward the rear until arrested by the stop face g, see Fig. 2, the efiect of which lever movement is to bring the cam e into action and to forcibly press the upper jaw toward the lower jaw. During the closing movement of the jaws, the ledge is of the upper jaw acts upon the loop 19 of the splice member to compress the latter, and the ledges h h of the lower jaw act upon the binder to upset the latter, and to bring the splice member into the plane of the binder, the upset or displaced portions of the splice member and of the binder being received into the channels it, i, Z, of the jaws. The splice member and the binder are thus displaced to effect a mutual interlocking of said binder and splice member, and during this operation the ledges on the working faces of the jaws act to retain the splice member in position, more particularly during the swinging movement of the upper jaw toward the lower jaw, the operations of pinching the metal parts 0 P having no tendency in this implement to shove the metal out of the way.

From the foregoing it will be understood that the implement embodies means for securing a relatively powerful leverage in order to upset the metal of the parts 0, P, and effectively lock the same together for holding the binder under tension.

After th implement is operated to close the jaws and thereby interlock the splice member and the binder, the lever is swung over toward ,the right and the spring opens the jaws, thus permitting the implement to be removed easily and quickly from the locked binder.

Having thus fully described the invention what I claim as new and desire to se-' mire by Letters Patent is I. An implement for joining the end porunder face with a plurality 'ofzchannels and with a ledge intervening said channels, the height of said ledge being less than the depth of the channels, the ledges and thechannel of the lower jaw being in registering relation to the channels and the ledge of the upper jaw, and means for imparting relative movement to said jaws.
